This is one of my favorite talks, and it is public!  Please enjoy.

From TEDxMarin:

What are we really? Our bodies aren’t really self-contained machines – they’re more like ecosystems. The recent explosion of research into our body’s microbial universe will change 21st century treatment of metabolic, immune and psycho-emotional disorders. What’s more, it will cast a whole new perspective on our metaphors, cultural assumptions, and the very identity of “self,” as described in this talk by cultural anthropologist Miriam Lueck Avery.
